Easy Journey to Other Planets Chapter One Antimaterial Worlds
When a man professes to belong to a particular faith--Hindu, Muslim, Christian, Buddhist or any other sect--and when he refers to a particular time and circumstance of birth, such designations are called non-sanatana-dharma. A Hindu may become a Muslim or a Muslim may become a Hindu or Christian, etc., but in all circumstances there is one constant. In all circumstances, he is rendering service to others. A Hindu, Muslim, Buddhist or Christian is in all circumstances a servant of someone. The particular type of faith professed is not sanatana-dharma. Sanatana-dharma is the constant companion of the living being, the unifier of all religions. Sanatana-dharma is the rendering of service.
In the Bhagavad-gita there are several references to that which is sanatana. Let us learn the import of sanatana-dharma from this authority.
There is reference to the word sanatanam in the tenth verse of the Seventh Chapter, in which the Lord says that He is the eternal fountainhead of everything and is therefore sanatanam. The fountainhead of everything is described in the Upanisads as the complete whole. All emanations of the fountainhead are also complete in themselves, but although many complete units emanate from the complete sanatana fountainhead, the sanatana remains unchanged.That is because the nature of sanatana is unchangeable. Anything that changes under the influence of time and circumstances is not sanatana. Therefore anything that changes whatsoever in form or quality cannot be accepted as sanatana. To give a material example, the sun has been disseminating its rays for hundreds and millions of years, and yet although it is a materially created object, its form and rays are still unchanged. Therefore, that which is never created cannot change in formation and quality, even though He is the seedling source of everything.
